You’ve probably heard that solar power is clean and green, but can it be installed on your house? In the infographic below we summarized what you need to understand before installing a photovoltaic system on your house.

A guideline on how we select the main components of a purely off-grid system, not a hybrid system in which the batteries back up a grid tie system

Fire Ratings Racking to Modules. How are modules rated vs how inverters are rated. What is type 1 and class A, B, or C fire ratings.

Weight Ratings of Roof Mountings. Are there industry standards? What are they?

There is increasing demand for battery-based solar PV systems everywhere. As utility agreements change, batteries offer improved economics and independence, however it is critical to choose the right type for the application.

Integrating the electronics for battery-based solar systems is the final step before installation. It can be very easy or tough, depending on the products you selected and the nature of the install.

Renvu does not have a team of installers to offer hands-on assistance to our customers. We focus primarily on a providing PV products. We do have an experienced sales engineering staff with prior hands-on experience installing PV systems. With this knowledge base, we can offer design assistance to our customers across the United States.

We can provide a PV permit package that can help with the installation. If you need an engineering stamp, this is an added cost that is quoted on a case by case basis.

To calculate how much solar energy you would need to produce you might be interested in calculating how much energy your heating, ventilation, and air conditioning systems use. However, HVAC load is complex and difficult to gauge without lots of data.

Of course! For permit package requested, be sure to contact our sales engineering team to make sure that we can offer support for your particular project. Read more for details here.

Here's why most PV professionals will choose to oversize the PV module DC STC power rating to the output rating of the inverter

I am looking to build a new home in the near future and want it to be totally electric and power supplied by solar.

I need 1 panel for my battery that operates an automatic lightweight gate at entrance. What do you recommend? I’m also interested in upgrading to a larger battery.

This information will generally be provided in the PV permit package by the assumed distance between rafters. For example, if you have 2’ on center rafters, and the flashing is mounted on every other rafter, then you should be installing a system with 4’ on center design.

Thank you for bringing this to our attention. We will check to see if we can expand our sites capability for this particular functionality. You may wish to try registering with Renvu.com to see if we can accept the email address there, or alternatively, email us directly at info@renvu.com to inform us of the issue and help you get started with a manually created quote by our sales team.

Off-grid design can be a very complex process, so here's a list of simple steps to assist you in getting a suitable off-grid PV system for your home.

The average price of a monocrystalline solar panel is difficult to determine. There are many different types of PV modules produced. Some are lower cost and optimized for large PV farms with MW level output.

For a successful installation of your solar system, you’re going need a couple of tools handy. Here are the tools for solar installations that you should have.

All of our installation manuals should be on our website underneath their respective product pages. If you purchase the permit package through us, you will have an engineered document to guide you through the installation.

The PVWatts calculator has a column for the $ value. How is that calculated?

In the United States, it took from 1954 to 2016 to reach a total of 1 million solar installations. Wood Mackenzie Power & Renewables and Solar Energy Industries Association (SEIA) recently released that the U.S. has now exceeded 2 million installations!

Sol-Ark has two models of hybrid all-in-one inverters: 8K (SOL-ARK-8K-48-ST) and 12K (SOL-ARK-12K-P). Here's a comparison of their inverters.

Which Tigo MLPE do you need? Explore our article about the different models to see which one is right for you.

With the Solar Mandate in effect, what is a building climate zone? How do I determine the minimum solar PV system size required for new construction?

The first task is to identify whether rapid shutdown is required for your commercial solar installation and to what extent.

The California Solar Mandate: How to Calculate Your Photovoltaic Requirements under the 2019 California Building Energy Efficiency Standards (Title 24, Part 6)

The “Solar Mandate” is the latest edition to the California energy code which introduces the requirement for photovoltaic (PV) systems to be installed on all new low-rise residential buildings.

Enphase’s partner, Solaria, has produced the most powerful AC Module currently available on the market for “Long Tail” installers and DIY-ers.

Are AC modules worth the extra cost? Here we will go over the basics of AC solar panels to help you make your decision on which solar panel you should buy.

Finding information about the Self-Generation Incentive Program (SGIP) can be tricky to locate, and it is often challenging to decrypt. Here, we offer a guide on the basic essentials of the SGIP, where to find more information, and how to apply for the program if you are eligible.

Commercial-scale battery energy storage systems (~100kW+ nominal power output) and utility-scale battery energy storage systems (~1MW+ nominal power output) are a rapidly growing sector of the variable renewable energy landscape.

The ampacity of the busbar refers to how much current the main panel busbar is rated for, and this can be found on the label of your main panel.

A supply-side connection or line-side connection is a form of interconnection that is typically used when your main electrical panel is not suitable to handle the inverter breaker and it is not possible to downsize the main breaker and upgrading the main electrical panel is not an option.

If downsizing your main breaker is not an option, and if your utility will not allow a supply-side tap, you may need to upgrade your main electrical panel with one with more capacity.

Generally, you can take the inverter maximum AC power in Watts and divide it by the operating voltage (240V for most residential applications).

If your main electrical panel is not suitable to handle the inverter breaker due to the limitation of the 120% rule or if your electrical panel is center-fed (100% rule may apply instead of 120%).

This is an article that teaches about how to use the 120% rule!

Adding a hybrid energy generation system with battery backup storage is beneficial for specific individuals that rely on a continuous and uninterruptible power supply all year long. Learn more in this article about the benefits of a hybrid system.
